N UT-LOCK.

To all whom it may concern:

Be it known that I, IVILLIAM R. GARNER, a citizen of the United States,and a resident of Palestine, in the county of Anderson and State ofTexas, have made certain new and useful Improvements in Nut-Locks, ofwhich the following is a specification.

This invention is an improvement in combination nut locks and washersespecially designed for use on railway rail joints, and the inventionconsists in certain novel constructions and combinations of parts aswill be hereinafter described and claimed.

In the drawings Figure 1 is a top plan view. Fig. 2 is an elevation ofthe inner side of a device embodying my invention. Fig. 3 is a detailsection on about line 33 of Fig. 1,,the nut and bolt being in place, andthe washer being partly broken away. Fig. 4 is a detail cross section onabout line 4t of Fig. 2, and Fig. 5 is a cross section on about line 55of Fig. 2.

In carrying out my invention I provide a body or top plate A, which maybe of a width about equal to the thickness of the nuts upon which thelock is to be used, and at the inner side of this plate A I provide thedepending washers B connected at their upper edges at B with the inneredges of the plate A, being preferably integral therewith, and beingcast of either malleable iron, or forged, or stamped integral with thesaid plate A, and the said washers B having the bolt openings B and onopposite sides thereof the depending arms B having at their lower endslateral inwardly project-' ing extensions B which underlie the bolt andincrease the bearing between the nut and washer by these lateralextensions 13 below the bolt when the locking device is applied fromabove. These washers, it will be noticed, in addition to serving aswashers for the nuts also look the locking device against anydisplacement in a direction parallel to the axis of the bolt.

The plate A is provided with the depending arms A shouldered at theirlower ends at A and beveled below the shoulders at A to facilitate theapplication of the arms on opposite sides of the nuts D to a positionSpecification of Letters Patent.

Application filed December 19, 1908.

Patented Aug. 3, 1909.

Serial No. 468,270.

Where the shoulders A will spring beneath the nuts D and lock the devicein place as against movement. in a direction radial to the bolt E.

The arms A when in engagement with the nut as shown in Fig. 8, preventthe turning of the nut and the accidental displacement of the lockingdevice in a vertical direction.

In applying the locking devices it will be understood that the nutsshould be l0os ened sufficiently to permit the driving of the washerplates B between the nuts and the back plate or angle bar. These washerplates it will be understood are attached to the top plate A at theirupper ends and the shoulder springs A are also attached at their upperends to the top plate, but all are detached thence to their lower ends.

I claim 1. A nut locking device comprising a main plate, washersintegral with and projecting at a right angle to said plate from itsinner edge and having a bolt opening, and arms on opposite sidesthereof, and provided at their lower ends with lateral inwardlyprojecting portions to hook below a bolt, and arms depending from themain plate and adapted to extend on opposite sides of the nut, andprovided with shoulders to spring below a nut, all substantially as andfor the purposes set forth.

2. The combination in a nut lock of a main plate having depending armsto extend on opposite sides of a nut and spring operating shoulders tospring below the nut, and a double armed washer to operate in rear of anut, substantially as set forth.

3. A nut lock comprising a plate to extend above a series of nuts,washers connected at their upper edges with the top plate at the inneredge thereof and extending down therefrom and having arms to underlie anut and to extend on opposite sides of a bolt and provided with inwardlyprojecting portions to engage below a bolt, and arms depending from saidtop plate and adapted to extend down alongside a nut and provided attheir lower ends with hooks to engage below a nut and with beveledsurfaces leading thereto all substantially as and for the purposes setforth.

4;. A nut lock comprising a plate to extend above a series of nuts, aWasher connected With said plate and adapted to underlie a nut, and armsprojecting from the said plate and adapted to extend down alongside anut and provided with shoulders to spring underneath a nut whereby tolock the device to a nut substantially as set forth.
